Incidence, Reinfection, and Discrepancy Between Sexual Practice and Anatomic Site Positivity of Sexually Transmitted Infections in Youth With HIV.

BACKGROUND: This study aimed to determine the overall incidence and reinfection rates of sexually transmitted infections (STIs) and the discrepancy between self-reported exposure history and anatomic site positivity of STIs among adolescents and young adults (AYAs) with HIV in Atlanta, GA. METHODS: Retrospective chart review was conducted on all patients 13-24 years of age at the Grady Ponce and Family Youth Clinic from January 1, 2009 to December 31, 2018. Data were collected on patient demographics, self-reported sexual history and STI events. First STI incidence and incidence of reinfections were calculated by dividing new cases over corresponding person follow-up time. RESULTS: A total of 626 sexually active AYAs with HIV were included in analysis. The mean age at first observation was 18.9 (SD: ±2.8) years; 72% were male, 92% were Black and 80% were horizontally infected. The cumulative first STI incidence rate was 45.49 cases per 100 person-years, and the recurrent STI incidence rate was 119.86 cases per 100 person-years. Among all Neisseria gonorrhoeae (GC) and Chlamydia trachomatis (CT) cases, the most common site of infection was the rectum (48.6% and 49.6%, respectively). Disagreement between exposure history and presence of GC or CT infection was statistically significant for nearly all anatomic sites and types of intercourse. CONCLUSIONS: AYAs with HIV in Atlanta have disproportionately high first and recurrent incidence rates of STIs, with many patients not reporting exposure at their site of infection. There is considerable need to increase screening for STIs, including routine extragenital testing for GC and CT, among AYAs with HIV regardless of self-reported exposure history.

Incidence and predictors of brain metastasis in colorectal cancer patients.

PURPOSE: Brain metastasis (BM) in colorectal cancer patients is rare and is associated with dismal outcomes. Our study aims to evaluate the incidence and predictors of BM in patients with colorectal cancer. METHODS: We performed a retrospective analysis (2010-2017) of patients with a primary diagnosis of colorectal cancer (CRC). Patients were stratified into two groups (BM vs. No-BM). Outcome measures were the incidence and predictors of BM. Multivariate logistic regression analysis was performed. RESULTS: A total of 230,806 patients were analyzed. A total of 0.30% (n = 691) of the patients were found to have BM. On multivariate logistics regression, bone (OR: 5.39 [3.36-8.65], p < 0.001), lung (OR: 3.75 [2.67-5.28], < 0.001), and distant node metastasis (OR: 32.75 [20.47-52.41], p < 0.001) were independent predictors of BM. CONCLUSION: Our study supports the low incidence of brain metastasis in patients with colorectal cancer. A unique set of characteristics is identified to confer an increased risk of brain metastases.

The role of preoperative anemia in patients undergoing colectomy for diverticular disease: does surgical urgency matter?

PURPOSE: Surgery especially in the emergent setting carries higher rates of morbidity and mortality. The aim of our study was to evaluate the impact of preoperative anemia on outcomes for patients undergoing colectomy for acute diverticulitis in both elective and emergent settings. METHODS: We performed a 4-year analysis of the ACS-NSQIP and included adult patients with acute diverticulitis who underwent colectomy. Patients were stratified into two groups based on preoperative hemoglobin levels, preop anemia and no-preop Anemia. Outcome measures were 30-day complications, anastomotic leaks, readmissions, mortality, and intra-/postoperative blood transfusion. We also performed a sub-analysis for patients who underwent emergent colectomy. RESULTS: Six thousand nine hundred sixty-three patients were included in the analysis, of which 37% (n = 2571) had preoperative anemia. Patients in the anemia group were more likely to have higher ASA class and receive blood 72-h preoperatively (5.4% vs. 0.2%, p < 0.01). Patients in the anemia group had higher rates of complications (35.4% vs. 24.7%, p < 0.01), unplanned readmission (9.2% vs 7.2%, p < 0.01), mortality (4.5% vs. 1.8%, p < 0.01), and intra/postoperative transfusion requirement (21% vs. 3.8%, p < 0.01) with no difference in rate of anastomotic leaks. On sub-analysis, 39% of the cases were completed in an emergent setting, 85% of which were due to perforation. Patients with preoperative anemia that underwent colectomy in an emergent setting had higher odds of intra/postoperative blood transfusion (OR 51.6, CI 3.87-6.87, p < 0.01) with no statistical significance in 30-day complications (p = 0.51). CONCLUSION: Preoperative anemia in patients undergoing colectomy for acute diverticular disease is associated with higher odds complications, readmissions, and intra/postoperative blood transfusions.

The Second Victim Experience and Support Tool: Validation of an Organizational Resource for Assessing Second Victim Effects and the Quality of Support Resources.

OBJECTIVES: Medical errors and unanticipated negative patient outcomes can damage the well-being of health care providers. These affected individuals, referred to as "second victims," can experience various psychological and physical symptoms. Support resources provided by health care organizations to prevent and reduce second victim-related harm are often inadequate. In this study, we present the development and psychometric evaluation of the Second Victim Experience and Support Tool (SVEST), a survey instrument that can assist health care organizations to implement and track the performance of second victim support resources. METHODS: The SVEST (29 items representing 7 dimensions and 2 outcome variables) was completed by 303 health care providers involved in direct patient care. The survey collected responses on second victim-related psychological and physical symptoms and the quality of support resources. Desirability of possible support resources was also measured. The SVEST was assessed for content validity, internal consistency, and construct validity with confirmatory factor analysis. RESULTS: Confirmatory factor analysis results suggested good model fit for the survey. Cronbach α reliability scores for the survey dimensions ranged from 0.61 to 0.89. The most desired second victim support option was "A respected peer to discuss the details of what happened." CONCLUSIONS: The SVEST can be used by health care organizations to evaluate second victim experiences of their staff and the quality of existing support resources. It can also provide health care organization leaders with information on second victim-related support resources most preferred by their staff. The SVEST can be administered before and after implementing new second victim resources to measure perceptions of effectiveness.

Probability of Regenerating a Normal Limb After Bite Injury in the Mexican Axolotl (Ambystoma mexicanum).

Multiple factors are thought to cause limb abnormalities in amphibian populations by altering processes of limb development and regeneration. We examined adult and juvenile axolotls (Ambystoma mexicanum) in the Ambystoma Genetic Stock Center (AGSC) for limb and digit abnormalities to investigate the probability of normal regeneration after bite injury. We observed that 80% of larval salamanders show evidence of bite injury at the time of transition from group housing to solitary housing. Among 717 adult axolotls that were surveyed, which included solitary-housed males and group-housed females, approximately half presented abnormalities, including examples of extra or missing digits and limbs, fused digits, and digits growing from atypical anatomical positions. Bite injury likely explains these limb defects, and not abnormal development, because limbs with normal anatomy regenerated after performing rostral amputations. We infer that only 43% of AGSC larvae will present four anatomically normal looking adult limbs after incurring a bite injury. Our results show regeneration of normal limb anatomy to be less than perfect after bite injury.
